Abstract

The main purpose for this invention is to provide an effective steering device for manoeuvring a boat in narrow passages e g when docking at a quay.
The most common arrangement with a conventional boat bottom is that the propeller and propeller house is placed in a thruster tunnel open to both sides of the boat below the water surface.
With more modem boats having a shallower hull profile a more effective solution is to have the propeller assembly lowered down through a recess in the hull bottom in order for it to be able to be below the water surface when required.. This is done by swinging the propeller assembly through a recess in the bottom of the boat as shown in fig 1.
This invention (in fig 1) fulfils the demands described above by having a propeller assembly (1) with a propeller (3) driven by a motor and placed at each end of a carrying arm (4) which is mounted in a pi fixture (A-A) (fig4) with pivoting axles (6) and which therefore can be swung down through the bottom of the boat and placed under the water surface.
